In the transfer and distribution of data by Application Link Enabling (ALE), the field selection defined by you in Customizing for the Material Master (in Maintain Field Selection for Data Screens ) is interpreted in the same way as in online mode. However, in ALE, the following separate transaction references are used for field selection at transaction level:
MAL1 (for creating materials)
MAL2 (for changing materials)
In online mode, the transaction references used for field selection at transaction level are:
MM01 (for creating materials)
MM02 (for changing materials)
This makes it possible to specify a different field selection at transaction level for ALE and for online mode.
Fields defined as not ready for input in Customizing for the Material Master are not transferred. The system issues a corresponding warning. Fields defined as required fields are checked.
