I have to add an additional line item in MIRO T-Code in Materials Tab as the delay delivery to reduce the material price.
Is their any exit available to add such kind of line items there.
Moreover will it impact the system in terms that the added line item will not get populated in the system.
one possibility is badi MRM_ITEM_CUSTFIELDS. Read carefully the documentation of the badi.
It will a create a new tab (not an existing one).
