Abap dump error

Hello

The problem we are facing is.. We have installed the recent patch in order to get TAN included in Form 16 and it is working fine in r/3 but in ESS it is throwing dump error.

The error states :

Error in Abap 4 statement when processing an internal table.

Program: HINCF161

When changing or deleting one or more lines of the internal table or when inserting in the table , 0 was used as the line index.

An index less than or equal to zero is not allowed.

Please suggest....
