Database error -901 at SEL access to table D020S

[Former Member]

When i try to run language import, i get error message "Database error -901 at SEL access to table D020S" and short dump is generated with DBIF_RSQL_SQL_ERROR and CX_SY_OPEN_SQL_DB. Similiar problem occurs when i try to generate programs using SGEN. I tried to read all records from D020S table, and all the records are displayed correctly.

The operating system is AS/400 (i5/OS V5R4).

Has anybody encountered similiar problem?

Unfortunately dltr3pkg did not solve the problem

[Former Member]

I found the solution. The problem was resolved by importing latest PTFs.

Hi,

I had exactly same problem i.e "Database error -901 at SEL access to table D020S" being displayed in SM21 followed with DBIF dumps, after QA refresh.

I deleted all the R/3 SQL packages and everything is fine. Now I can't see any such logs.

Sai R.

Hi,

SQL0901 shows typically in the joblog before that error the real issue, as this one is very generic. So, you should look there and let us know.

On the other hand, I would always try to stopsap, dltr3pkg and startsap first ...

Often, the problem disappears ...
