If you need, you can create the document manually. The required fields are: Company, Contract, Entity, and Basis. 
The "Tax Invoice Received (create)" form. The Main tab
In the Company field, select a supplier, an individual or a legal entity, whose tax invoice you need to create. The Contract field (not available for the Advance transaction type) is populated automatically with the default contract of the selected supplier. If necessary, you can select another contract of this supplier (to open the list of contracts, click in the Contract field, then select Show all).
...
<Auto> in the Number field indicates that an internal number (in the database) for this document is assigned automatically when you save the document.
The From field is populated automatically by the current business date. You can select another date if necessary. The corresponding input VAT amount will be considered as recoverable amount starting from this date.
In the Transaction Type field, you can select one of the following options:
- Receipt: To indicate that this tax invoice received is for received goods and services. This enables the Summary check box and the Basis tab.
- Advance: To indicate that this tax invoice received is based on the payment expense (or cash expense, or cheque payment expense) issued for the supplier as an advance payment. This brings up additional fields (VAT Amount of Planned Supply and Total Planned Supply) at the bottom of the form, which are auto-populated from the payment (basis document) and show the planned VAT and total amounts.
- Other: To indicate that this tax invoice received is related to a document of other type. In the Related To field, which is available only for this option, you can select a document of the Input VAT Transaction type.
...
In the Basis field, you can select one of this supplier's documents of the following types:
- Invoice Received, Subcontractor Report, Additional Expenses (transaction type: Receipt)
- Input VAT Transaction (transaction type: Other)
- Payment Expense, or Petty Cash Expense, or Cheque Payment Expense (transaction type: Advance)
Once the basis is selected, the data is copied to the document from the basis. If you have made changes to the document that you would like to cancel, you can click the Fill by Basis button to reset the data to the data from the basis.
A string below the Basis field (not displayed if Advance is the transaction type)—on the screenshot above, Basis Currency: AED—indicates the currency of the document selected as the basis. In case the basis document is not in the national currency, this string also shows the exchange rate of this currency with respect to the national currency, and then, on the Inventory and Services tab, the item and VAT amounts will be shown in both currencies. The exchange rate to be used for amount conversion must be equal to the rate published by the UAE Central Bank for the date of the supply. For details, see Currencies.
The document totals and other Information
For the document with other than the Advance transaction type, the VAT field shows the total VAT amount calculated for the document, and the Total Due field shows the document total.
If Advance is selected as the transaction type, there are additional fields at the form bottom. 
The "Tax Invoice Received (create)" form. The Main tab for the Advance Transaction type
Generally, these fields (VAT Amount of Planned Supply and Total Planned Supply) are populated with the data from the purchase order which was used as the basis for the advance payment.
