WHERE ASTDTA.ICPRTMIA.IARCC9='ACS'
AND ASTDTA.OEINDLID.IDCOM#='001'
AND ASTDTA.OEINDLID.IDPRT# LIKE 'ACS%'
AND ASTDTA.ADRESSAD.ADSFX# = SUBSTR(ASTDTA.OEINDLID.IDGRC#,9,3)

I am unsure if I interpreted what was attempted to be expressed as the desired effect, but I offer [given my interpretation]:

WHERE ASTDTA.ICPRTMIA.IARCC9='ACS'
AND ASTDTA.OEINDLID.IDCOM#='001'
AND ( ASTDTA.OEINDLID.IDPRT# LIKE 'ACS%'
OR ASTDTA.OEINDLID.IDPRT# LIKE 'FR%'
)
AND ASTDTA.ADRESSAD.ADSFX#=SUBSTR(ASTDTA.OEINDLID.IDGRC#, 9, 3)

P.S. The use of correlation identifiers protects against excessive changes that would be required given any change in a schema or table name were required; that also IMO makes the SQL much more readable. Also note that a space was added after each comma in the SUBSTR scalar to make the expression functional globally. FWiW the above WHERE-clause rewritten using some correlation names makes the predicates fit on a line with fewer characters and would allow the entire WHERE-clause to remain unchanged when the table or library name for the table-reference had changed, given the correlation-name was left unchanged:

WHERE ICP.IARCC9='ACS'
AND OEI.IDCOM#='001'
AND ( OEI.IDPRT# LIKE 'ACS%'
OR OEI.IDPRT# LIKE 'FR%'
)
AND ADR.ADSFX#=SUBSTR(OEI.IDGRC#, 9, 3)
