This is a language requirement. Level No. 01 is used for records. There cannot be a table of records.

This is a language requirement. Level No. 01 is used for records. There cannot be a table of records. So the use of OCCURS clause in 01 level is not allowed.

An occurs clause may be used on levels 02-49 only.That is the occurs is not valid for the 01 level since it must be used for defining fields not records.Occurs is used for repeated occurance of fields then not records.

for example:- IT IS NOT VALID TO CODE

01 IN-REC OCCURS 15 TIMES.
