If you search for the phrase “inconsistencies in the G/L Entry table” you will find this has been posted on many many occassions and I beleive it is always caused by a modification to the system not taking into account all processing requirements - my advice is to contact your partner.
Inconsistency errors are thrown mostly when system finds that debit & credit entries are not tallying while running the posting routines. This could be due to several reasons like rounding in VAT setup, application of item charges to items amountwise etc.
