As enterprises embrace the operational simplicity and comfort of SaaS companies, there’s been one main holdout. Traditional back-office ERP programs have largely confirmed proof against cloud migration due to the query of what to do with all of the customizations? Again within the Y2K rush to modernize backend programs, typical observe was to place all of the adjustments contained in the core utility code. And that’s why, a few years again, we posited that traditional enterprise programs can be the final frontier for cloud adoption.
And that’s the place we get to SAP. In relation to ERP and related back-office purposes, no person touches SAP’s footprint. Based on the corporate’s personal figures, 77% of the world’s transaction information by income touches SAP programs. Whereas that doesn’t essentially imply that SAP Enterprise Warehouse (SAP BW) touches all that information, it nonetheless has an unlimited footprint with operational reporting, and there are many years of code that’s simply too pricey and disruptive to vary. And so, in the event you have been an ECC or BW consumer who wished to ditch your information middle, your alternative was managing your individual deployments in AWS EC2, or the like.

Reply for the Put in Base
Final fall, SAP unveiled SAP BW Bridge, its SaaS reply for the traditional SAP Enterprise Warehouse (BW) put in base. SAP BW Bridge gives a option to re-platform to the cloud whereas protecting all of the ingrained enterprise logic and customizations intact. It creates a brand new workspace (“area”) on SAP Knowledge Warehouse Cloud (DWC), with the objective of enabling the huge SAP BW put in base to elevate and shift, taking the operational benefits of cloud deployment minus the disruption, or at the very least, the brunt of it.
Supporting BW variations from 7.3 and later, BW Bridge is an atmosphere inside DWC supporting the traditional ABAP code and artifacts utilized in BW, working immediately hooked up to a buyer DWC tenant. The excellent news is that BW Bridge takes benefit of an current DWC to assemble: the area. DWC was arrange with the concept that completely different line organizations would need their very own workspaces, so legacy BW environments might as effectively be considered one of them.
So that can enable the customizations which can be typical of legacy SAP BW implementations, comparable to custom-made income reporting durations, to remain intact. It avoids the duty of rearchitecting customizations that may in any other case be vital for transferring BW apps to DWC. In traditional SAP apps (together with BW), they have been carried out within the core ABAP code, whereas with SAP cloud SaaS companies, comparable to DWC, the bottom code is left untouched with customizations carried out as configurations atop it.
Not surprisingly, on condition that this was referred to as BW Bridge, it retains ABAP code intact. Clients can both simply convert and migrate the metadata of their current BW implementation (a “shell” conversion) or ship each metadata and information itself (a “distant” conversion) to the DWC area goal.
Developer Nostalgia Tour
However the flip facet of sustaining the traditional atmosphere is that the event expertise is a nostalgia tour again to an Eclipse-based atmosphere, with a toolchain that’s pretty complicated sporting the feel and appear of one thing out of the early 2000s. Knowledge and processes are managed inside a cockpit utilizing Eclipse-based traditional SAP information modeling instruments. Connections to the BW on-premises supply require the usage of:
- Good-Knowledge-Entry (SDA), which instantiates read-only views of tables which can be to be moved to the cloud;
- SAP’s Operational Knowledge Provisioning (ODP), the connector for legacy SAP programs, which performs the information extraction; and
- DWC’s Knowledge Builder, which imports tables into the DWC area.
As soon as BW information has been populated to DWC in its personal area, clients can run their current operational analytics and reporting applications, and so they may also share BW information with different areas by way of Cross-House-Sharing. And sharing is not only restricted to the BW Bridge area; information property loaded into the BW Bridge area may be shared and remodeled to be used in areas with the extra fashionable DWC information fashions.
Knowledge Acquisition and Staging
As presently designed, SAP BW Bridge is primarily meant as an information acquisition and staging layer — which has been the mainstay for BW. Different capabilities, comparable to planning, are exterior the scope of BW Bridge; as an alternative, SAP directs BW clients to SAP Analytics Cloud (SAC) Planning, which for now’s a separate providing; later this yr, SAP will add assist SAC planning on prime of DWC primarily based information fashions.
The situations for SAP BW Bridge are, not surprisingly, centered round bringing SAP legacy information sources into the fashionable cloud information warehousing world. It may embrace people who wish to replicate their current BW atmosphere and operational reviews however in a managed cloud atmosphere. And naturally, it may contain migrating extra fashionable BW/4HANA on-premises as effectively. And, as famous above, with cross-space sharing, BW information could possibly be shared with different greenfield analytics, and combined with information from different sources, developed in DWC.
SAP BW Bridge is an acknowledgment that, for traditional or legacy programs to make it into the cloud, cloud SaaS suppliers have to supply extra flexibility to accommodate the sorts of customizations that permeate legacy programs. That was the rationale behind AWS’s latest introduction of RDS Customized that offers clients management of extra knobs for his or her Oracle and SQL Server implementations in comparison with AWS’s commonplace service.
It’s a cautious balancing act, as a result of at what level do customizations compromise the economics of scale within the cloud? That was what doomed the prehistoric technology of Software Service Suppliers (ASPs) that emerged throughout the ERP adoption wave of the Nineteen Nineties. The going notion then was to unburden enterprises underneath the stress to modernize programs for Y2K by at the very least having their ERP programs hosted. The diploma of customizations for each buyer made it too pricey for service suppliers to supply significant financial savings.
Guardrails for the Cloud
The answer within the cloud has been to place guardrails, such because the areas that SAP has adopted with DWC. As famous above, SAP is interesting to the group of ABAP builders who’ve been sustaining BW situations. On the horizon, SAP plans to automate migration with a toolset that checks readiness of SAP BW and BW/4HANA objects (comparable to information switch processes (DTP), DataStore objects, InfoObjects, transformations, course of chains, and many others.) after which robotically transfer these greenlighted.
That’s a superb begin. However in fact, as a result of we’re by no means glad, right here’s our want checklist. We’d like such a device to additionally troubleshoot, and to the extent potential, automate fixes of objects into compliance. Really, let’s take that one additional. We’d prefer to see tooling that robotically replicates a snapshot of the present atmosphere, encompassing information and code, and robotically carry out the required conversions to make the objects prepared for transferring. That’s with the notion that sooner or later, builders who’re going to be charged with transferring and sustaining BW situations, might not have the identical ABAP abilities.
Both means, SAP BW bridge is an effective instance of the best way to get these cussed legacy programs into the Twenty first-century cloud.
