hello All,
getting below dump while executing ML81N. Attached completed log of dump in attachments.
appreciate your help.

Error analysis
When changing or deleting one or more rows in internal table
"\FUNCTION-POOL=MLSP\DATA=INT_SUBDIV[]"
or when inserting rows into table "\FUNCTION-POOL=MLSP\DATA=INT_SUBDIV[]", 0
was used as the row
index. An index less than or equal to zero is not allowed.
The error can occur when using the following additions:
1. "INDEX idx" for specifying the row number in table
"\FUNCTION-POOL=MLSP\DATA=INT_SUBDIV[]" where
the row is to be changed, inserted or deleted.
2. "FROM idx" for specifying the start index when deleting a row area
from or inserting a row area into table
"\FUNCTION-POOL=MLSP\DATA=INT_SUBDIV[]".
3. "TO idx" for specifying the end index when deleting a row area from
or inserting a row area into table "\FUNCTION-POOL=MLSP\DATA=INT_SUBDIV[]".
When the program terminated, the table contained 0 rows.
