Absence valuation rules

Hi Payrol gurus,

I have requirement on creating new absence types and link those with Wagetypes in Payroll. I have no issue understanding that. Issue is that i see rules defined upto 97 in t554L table. When I try to link the Wagetypes in table T554c, those rules are assigned to diff groupings and difff wagetypes. If I make change to rule cty grouping 10 grpg 01 and attach whatever WType. But those rules are assigned to diff WTs. Upto what digit can we create rules in table t554L? Can someone help?
