Implementation of ETag for write services

This article details an approach for implementing ETags in OData write scenarios in SAPUI5 applications.

Traditionally SAP GUI applications have utilized pessimistic locking using lock objects to ensure data consistency in parallel usage scenarios like single material number being edited by two users concurrently, same employee’s work schedule getting updated in parallel in two sessions, etc.

Under the HANA hood of an ABAP Managed Database Procedure

I’ve been looking into ABAP managed database procedures for HANA recently and decided to take a look at what’s actually created under the hood in the HANA database when an AMDP is created.

I created a small test class in our CRM on HANA system with a method to read a couple of columns from the crmd_orderadm_h table using sqlscript. The method takes one input parameter IV_OBJECT_ID and has one export parameter ET_ORDER.

Configure ABAP webdynpro component into CRM system via Transaction launcher

THINK twice why you want to include an ABAP webdynpro component into CRM UI, as in CRM application it is not recommended to use ABAP webdynpro to develop UI. In some case for example, PDF preview is far more convenient using standard ABAP webdynpro control “Interactive form”. However if you would like to achieve the same via webclient UI, much more development are unavoidable.

Send web push notifications using ABAP through OneSignal

Traditionally (in ABAP-land), in order to notify a user about something in SAP, it meant sending an e-mail to the user mailbox. It works most of the time until the user gets sick and tired of all the emails and sets up a rule to block all incoming e-mails from the SAP system or sets a rule to route it to the spam folder.

Then, came along mobile / Fiori applications where we’re now open to the world of real-time push notifications directly on your mobile device – ding! Obviously, this works great when you’re looking at your phone 24×7 and it’s always within reach.
