There is a Function Module: MEASUREM_DOCUM_RFC_SINGLE_002 that you can use to read documents if keys are known. When there is no RFC module to get a list of $foo according to a set of selection criteria, it is possible to use RFC_READ_TABLE to get the keys from db directly.
Function Module MEASUREM_DOCUM_RFC_SINGLE_002: RFC Measurement document: Individual processing, Change/Display or Read
With use of this RFC, following remote calls can be used:
Remote dialog (WITH_DIALOG_SCREEN = 'X')
Remote dialog in display mode (EDIT_MODE = ' ')
Remote dialog in change mode (EDIT_MODE = 'X')
Remote reading of measurement document data (WITH_DIALOG_SCREEN = ' ')
Apart from when an EXCEPTION occurs, the measurement document data (structure IMRG) is always returned.
After a remote dialog in change mode, the redundant fields of the measurement document in the calling system can be synchronized.
