convert solix_tab to RAW 1022

hi,

I am converting smartfrom otf to binary using SX_OBJECT_CONVERT_OTF_PDF. the data type of content_bin is SOLIX_TAB, which is RAW (255). I want to convert this into SDOK_SDATX which is RAW (1022). I have used below code to do that, But I am getting dump in FM  SX_TABLE_LINE_WIDTH_CHANGE  'Invalid partial field access: Length is too large'. Am i Missing something? is there a better way to do this?

Dump text:

In the executed program "SAPLSX03", the system attempted to access the field

"CONTENT_IN" of the type "u" and with the length 127 using the length 255.

However, a partial field access with a length specification that is

larger than the field length is not allowed.
