Change Log variants - How it works in different scenarios

Symptom

Change log variant does not work as expected in some cases . Both ODSR* (activation) and REQ* (upload) requests will be deleted in case
that flag Delete Activation  Requests Only, No Load Request  as not been set . From the new release this should not be the case. When the Flag is not set
then only the REQ* requests should be deleted, And Incase the flag is set then only ODSR* requests should be deleted.

But in some cases this does not work as expected !!

Causes

If The variant has been saved the last time before the correction of SAP Note 1618423 has been  applied.

Before the implementation of the correction the system worked as followed:

•    Set the flag: Only ODSR*
      requests will be deleted
•    Set no flag: Both ODSR* and
     REQ* requests will be deleted

After the implementation of the correction the system works

as followed:

• Set the flag: Only ODSR*
  requests will be deleted
• Set no flag: Only REQ*
  requests will be deleted

Resolution

• Goto change mode (Edit mode) of the Process variant.
• Make a dummy change and Save.
• Revert the dummy change and Save again.

After applying these steps you should see the following entries in table  RSPCVARIANT:
