Validate Storage Type Indicator for Stock Placement and Removal

When loading the Warehouse Management view the Storage Type Indicator must exist in the T305 table. The functional team can create it using the SPRO transaction (see image on the right).

Checking to ensure that the value is populated prevents a false-negative by not checking for a blank LGNUM value. A simple SELECT SINGLE operation determines if the value is present in the T305 table.

if IMMH1-LTKZE ne ''.
  select single LGNUM from T305 into BMMH1-LTKZE
   where LGNUM eq IMMH1-LTKZE.
  if sy-subrc ne 0.
    write: / IMMH1-MATNR, IMMH1-LTKZE, 'Invalid location (LTKZE).'.
    skip_transaction.
  endif.
endif.
if IMMH1-LTKZA ne ''.
  select single LGNUM from T305 into BMMH1-LTKZA
   where LGNUM eq IMMH1-LTKZA.
  if sy-subrc ne 0.
    write: / IMMH1-MATNR, IMMH1-LTKZA, 'Invalid location (LTKZA).'.
    skip_transaction.
  endif.
endif.
