RMSTS_CHAPTER is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "RMS-TLS: Chapter Information for Output Objects" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_RMSTS_CHAPTER TYPE RMSTS_CHAPTER.
The RMSTS_CHAPTER table consists of various fields, each holding specific information or linking keys about RMS-TLS: Chapter Information for Output Objects data available in SAP. These include CHAPTER (Chapter Numbering of an Output Object), CHAPTER_LEN (Length of the Chapter Numbering for an Output Object)... See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
