# Verification fields

A generic verification feature is available that goes beyond the standard SAP verification profile logic. It is possible on any input screen to add a verification field that needs to match another field with data on the screen before one can proceed.

On any input screen, such the Planned PI Count screen, it is possible to add a verification field, for example material number, to ensure that the user has to enter the material number of the item being counted.

A new field can be added to the screen that needs to match exact the field it is to verify against followed by the suffix “\_VERIF”. e.g., `ISEG-MATNR_VERIF` will verify against the field `ISEG-MATNR`.

The feature is activated using the field class /TCTM/WM\_APP\_FIELD\_VERIFY assigned to the “\_VERIF” field.

If verification is to be mandatory before the user can leave the screen, then the “\_VERIF” field needs to be marked as “required”.

**Note**

If a field is suppressed in the app, its corresponding verification field is also suppressed. For example, if the selected material is not batch-managed, the batch verification field will be suppressed.
