[SAP MM] Trigger release strategy even for reduction of PO value

 At times, there is a a situation where the business requires a release strategy to be triggered if there are any changes to the purchase order document value either increase or decrease of document value.

In general, standard SAP does trigger a release strategy if there is an increase in document value but however, if there is any decrease in the document value system doesn't trigger release strategy.

This post covers the technical changes that we have to make to trigger release strategy if there is any decrease in the document value to that of the released amount.

Release strategy at purchase order level is triggered based on the function module - 'ME_REL_STRATEGIE_EKKO'

so we are required to make changes in this FM to accomplish this requirement.

Perform reset is used to reset the release strategy post-release of the document.

IF cekko-gnetw GT f1.
          PERFORM reset
            USING e_frgst e_frggr
                  e_frgzu e_frgkz e_frgrl.
          e_reset = 'X'.

We have performed the below changes to perform release reset post-purchase order release.

data: F2 type F.
f2 = cekko-gnetw * t16fb-tlfae / 1000.
wait UP TO 2 SECONDS.
f2 = f2 + cekko-gnetw.
ELSEIF f2 <> f1.
PERFORM reset
            USING e_frgst e_frggr
                  e_frgzu e_frgkz e_frgrl.
          e_reset = 'X'.
