Front-end memory and limitation cells of the BEX Analyzer

Hi BI experts,

After BW upgrade from BI 7.3 to BI 7.4 some heavy workbooks stopping to work, the error is "Client Out of Memory", the cause of this error is the memory capacity of .NET framework, this process can allocate a maximum of approximately 1.2 gigabytes (GB).

The notes 1040454 and 1411545 says that it´s possible to execute something like 750,000 cells but we made some adjusts and we could increase it until 1,800,000 cells, below some configuration we´ve made:

Query Designer:

Result Rows Always

Supress;

Display as Text or key;

Supress Zeros as Active (All Values = 0) and Effect on rows and columns.

Bex Analyzer:

Display Sort Icons Disable;

Apply formating Disable;

Allow navegation Disable;

We need some orientation how to further increase this limitation, or leaving the query lighter or increasing the memory limitation of .net framework or backing to BEX 3.5 funcionalities.

Has anyone encountered such problems in the update? Some alternative solution ?

Thanks !
