Assign Incompletion Forms to the Delivery Item Types in SM30 - V_TVLP_VUV
 

Define the Status Group in SM30 - V_TVUVS

You use this function to block a document for delivery, billing, or pricing etc.

In an incompletion procedure you group together the fields that are to be checked for completion. If you have not entered data in one of the fields in the document, the document is incomplete. Depending on the status group you can block certain subsequent activities for the document.

For every field in the procedure you also have to define whether a warning message should be issued during processing if no data is entered in this field.
