SAP Note 21440 - PC entry: Access outside area

Symptom:

The PC entry terminates when you try to enter a data entry form (error BASE/1133).

Cause and prerequisites

The data entry form has too many pages or lines

Solution
If the number of lines of a data entry form is below 999 lines (lines, value lines and totals, underscores), a TAB,IND file with the following contents can be created on the PC in the directory of the PC entry:
xxxxyyyy
I I > number of items
I > number of pages

for example,: 01000999 -> 100 pages, 999 lines.
Note: If the file TAB.IND does not exist, the program uses the internal value 020000400, that is, 200 pages and 400 lines.

If you still cannot enter a data entry form despite of this adjustment, you have to split up the data entry form into several smaller ones.
