I have created a Web Service:
DEFINE CLASS Fishers_AccpacWebInterface AS Session OLEPUBLIC

In certain of the functions I open tables in order to update them, in SHARED mode: USE <tablename> ALIAS <alias> SHARED.

I then FLOCK() or RLOCK() as required.

Then I APPEND BLANK and GATHER MEMVAR or REPLACE specific fields.

e.g. 
     USE ARDATA\ARCUST01 ALIAS a_arcust SHARED
     IF FLOCK("a_arcust")   
       SELECT a_arcust
       APPEND BLANK
       GATHER MEMVAR MEMO
       UNLOCK IN a_arcust
     ENDIF

When I run the class from VFP by declaring a newobject of the class locally, this code executes perfectly, but when I run it as a Web Server whenever I try to APPEND BLANK or REPLACE I get an error: Error: 1429 OLE IDispatch exception code 0 from Fishers_AccpacWebInterface ....... Cannot update the cursor A_ARCUST, since it is read-only. 111..
