If you need to use indicators, do not use the ones defined in the generation standards. Preferably use high indicator numbers that do not interfere with the indicators used by the management rules, by the PROTECT instructions, etc.
The indicators used by the management rules start in ascending order with the indicator numbers not used in the standards for every transaction. Each field containing at least one "PROCEDURAL_RULE xxxx FIELD" or "PREPARE_MSG xxxx FIELD" instruction needs an indicator.
