How To Fix GG521 - (Long text) Specify field name or number of line items per collect

SAP Error Message - Details

• Message type: E = Error

• Message class: GG - Messages for FI-SL customizing

• Message number: 521

• Message text: (Long text) Specify field name or number of line items per collect

What causes this issue?

You specified neither a field name (most selective field) nor a maximum
number of line items processed as a group for each collect (package
size).
Specifying these parameters is required to generate the creation
program.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

The logic of the repair program that is generated and called is
determined by these parameters:
If you maintain both parameters, the less critical program variant is
generated (see below). In other words, the collect counter determines
the procedure.
Entry of a selective field that is a key field ('logical' for
transparent tables) for line items as well as for the summary table
(default ist 'RACCT'):
Important:
This logic requires sufficiently large 'table spaces' (temporary
database spaces - see Note 2425 for an overview), because each table
access is sorted in the line items.
The generated program reads the line items sorted (by the specified
field, for transparent tables). When the field value is changed, the
program adds an internal table to another internal table, which is then
inserted in the summary table.
In the case of smaller table spaces, you should choose the second input
option, which has a main memory-oriented logic:
Entry of a number of line items per collect (an advisable number is
10000, but keep in mind that an entry in this field causes the field
name entry in 1) to be ignored):
The generated repair program does NOT read sorted. Instead, it performs
a collect with an internal table.
This logic is generally somewhat faster and gives you the advantage of
being able to choose smaller table spaces than in the first case.
Some disadvantages:
The number of summary records that can be created in each program run
is limited to 100000 in this version. You have to partition the data
accordingly using the selection options. To completely restore the
summary records, you may have to start the program more than once.
Also keep in mind the following:
If you want to start several parallel runs for ONE table, you need to
execute main program RGUREP01 as the first run. For all further runs,
start GENERATED program RGUREP02. Also remember that the data
quantities are disjunctive.
