Transfer structure 0BILL_CAT_TEXT_PA does not exist

Hi,

Thanks in advance.

I am trying to create transfer rule for master data data sources.For most of the data sources I am getting transfer structure does not exist example : Transfer structure0BILL_CAT_TEXT_PA does not exist

In the data source field length is 60 CHAR and field name is KEY1(Key Field for DataSource for Text). I am assigning Infoobject called 0BILL_CAT with length of CHAR 1.

Without assigning this field It will be activated but data will not come.

For most of the text data source sap used field name called KEY1 and KEY2 like that those field's length is 60

help me in this matter.

Thanks

Krishna
