SAP Error Message - Details

• Message type: E = Error

• Message class: FRMLMSC - RMS-FRM: Miscellaneous Messages for Formula

• Message number: 224

• Message text: Multilevel loop: Substance &1

What causes this issue?

The system takes loops over multiple levels into account when exploding
a formula.
This means that a substance SUB_1 may be the input substance in a
formula whose output substance is indirectly used as an input substance
in another formula whose output substance, in turn, is SUB_1.
The multi-level loop is indicated by the indirect relationship of the
relevant formula components (across n explosion levels).
