CL_SALV_TABLE - refresh using a RTTS defined dynamic table

Former Member — Wed, 10 Mar 2010 21:04:57 GMT

Hello,

I have defined a dynamic table using the RTTS method cl_abap_tabledescr=>create; the structure definition contains standard fields, custom fields and fields representing characteristics. The result a field symbol defined as standard table, <gt_data>. I'm using this table then to display a simple ALV list using cl_salv_table=>factory.

Problem: refreshing the data does not work. After the data has been changed (by jumping into the transaction and back to the ALV from a hotspot event), I re-read the data, CLEAR, UNASSIGN and ASSIGN the <gt_data> table again and call the cl_salv_table=>refresh method. The data in the <gt_data> table is being correctly set (verified via debugger), but the ALV does not update.

Any ideas?

Hi Hans-Peter,

Not quite sure I understand the steps. I would expect that you have a global field symbol that represents your table. I'd expect that you'd construct this table once via RTTS functionality and then keep using that specific instance. The UNASSIGN/ASSIGN step sounds a bit suspicious to me, because it seems as if you're creating a new instance, whereas your ALV still points to the old instance you created. So then when calling the [refresh_table_display|http://help.sap.com/saphelp_erp2004/helpdata/en/0a/b5531ed30911d2b467006094192fe3/frameset.htm] method your updates might not take effect, because ALV still has the reference to the previous table you've constructed.

Cheers, harald

Harald,

thank you for pointing me in the right direction - you are correct, I ran through the RTTS definition twice. I now only do a CLEAR for the field symbol and replace the contents, but not the instance.
