I am using the enhancement MM06E005 to add custom fields on the subscreen. i have created a table control there and i am trying to use two push buttons, one is for adding entries to table control and another one is for deleting.
But the problem is , system is giving an error saying this (custom function codes) is not available in the table T168F. This is a table where all the function codes for the purchasing document(contract) is mentioned.
Any body knows how to go about this problem. Do we need to contact with SAP for this.
