good morning. We are regular importers and when accounting for the GST on import record the gst basis value with gst tax code, and offset it with the gst basis value with N-T tax code, so that the actual GST levied calculates as tax correctly. This has always worked, and this morning I processed one bill in this manner, no problem. Now I have just processed another bill in the same way - and while the tax amount has calculated correctly, it is not included in the total amount field of the bill. Hoping someone might have a clue as to why this is not working. Same supplier as previous. screen shot attached.
