hi,
i am getting the following errors in my natural online system.
error code 1301 and 3055.

1301 means - The construct of the arithmetic expression generates an intermediate result with too many digits.

3055 means - An attempted format conversion was not possible due to incompatible data formats or other compatibility problems. During a read-type operation, a field defined with the SQL null (NC) option contained a null value, but the format buffer held no "S" (significant null) indicator field. Additions 2 may contain the field name in the leftmost two bytes; the rightmost two bytes may contain the offset into the record buffer.

i am new to adabas and trying to fix the problems. i have checked the line where the error code is occuring. for 1301 there is a subtract statement and for 3055 there is a read statement. but i dont understand how to rectify the issue.

the system is being used for many years and there were no issues anytime and was very stable. but recently we have upgraded natural and adabas to higher versions. so i do not understand if the problem is because of the upgradations or really with the code.

kindly suggest what needs to be done.

regards
vamshi
