DUMP Fetch Next Cursor Instruction after upgrade SAP BASIS to 740

Hello experts,

I really need your help.

I have a program that uses the following abap code. After upgrade to SAP Basis 740 this instructions is always performing dumps DBSQL_ILLEGAL_SWITCH and there is no way I can find what pattern it is (it does not have the same behavior with the same selection screen variables):

open cursor gv_cursr for

select tknum tpnum vbeln from vttp

for all entries in gt_outpt

where vbeln eq gt_outpt-remessa.

do.

*** Ini Vanda Roxo 01.09.2014 - Validação do sy-subrc após uprade.

* if sy-subrc eq 0.

fetch next cursor gv_cursr

into table gt_delss package size 50000.

if sy-subrc eq 0.

sort gt_delss by vbeln.

delete adjacent duplicates from gt_delss comparing vbeln.

append lines of gt_delss to gt_vttps.

else.

exit.

endif.

* endif.

enddo.

close cursor gv_cursr.

free gt_delss.

sort gt_vttps by vbeln.

I did not write this code, but I think the goal was to read VTTP data without a key fields, so they used this instruction because the volume of records returned was huge.

Can you please help?

Don't know what to do at this point.

Thank you!

😊

Best regards,
