Query on memory utilization by SAP_CONVERT_TO_TEX_FORMAT

[nagaraosunkara]

Hello All,

Facing a weird issue with memory consumption on usage of SAP_CONVERT_TO_TEX_FORMAT. PFB the details of the issue:

Program logic:

We are fetching 200,000 records into an internal table and using FM 'SAP_CONVERT_TO_TEX_FORMAT' to separate entries with '|' as separator, and data is downloaded as zip file from the internal table. 

Issue:

We have to download close to 1,900,000 entries, so we are splitting entries into 200,000 as a single block and processing this data.

During fifth iteration 184,000 entries are copied into internal table (as per period logic), and once the data is downloaded and goes for next iteration of 200,000, it fails with error 'TSV_TNEW_PAGE_ALLOC_FAILED'

Analysis:

While I was during memory analysis in debug mode, i've made a strange observation.

Until the 184,000 entries were downloaded I see the total memory consumption as 3,123,909,208 (ABAP mem was 2,534,342,234, whereas when the new set of 200,000 entries were being downloaded it suddenly increases to 4,514,178,208 (ABAP application total memory was 3,536,909,590)

This was observed after usage of SAP_CONVERT_TO_TEX_FORMAT.

Any pointers in sudden jump of total memory in memory sizes external session, when ABAP application memory usage remains same?

Thanks & Regards,

Naga
