Negative Stock Check
For IM postings, it is possible to prevent stock in a storage type from becoming negative. To do this, in the appropriate storage type records you must leave the field Allow negative stock blank (deselected). If this field is not selected, you can prevent negative quants from existing in the storage type depending on the settings in table 160M.
Setting Error or Warning Messages for Negative Stock Check
In table 160M, you can control whether the system issues an error message, a warning message, or no message at all when negative stock is posted. You can influence the type of message by using the parameter MSV in the user master record.
You create the key for Table 160M as follows:
The field Cat in Table 160M the system controls whether an error message, a warning message, or no message at all is to be issued.
If the parameter ID MSV in the user master is not maintained, the system accesses the table using version 00.
