Access sequence for services in sap MM

Hello There,

I have a requirement to create condition table for service using z field (KALSK:Pricing schema for vendor). I have included the field in KOMP structure under append structure ZAKOMPAZ. But this is not coming in the field catalogue when creating condition table for services. So I am not able to create access sequnce using this table. I am using SAP 4.6 version

Thanks in advance.
