<p>Hello Bo et al,</p>
<p>Thanks very much. I upgraded to 3.16.4 with some improvement.
Fields in the source but not present in the target were lost.</p>
<p>However, the Refactor tool worked well. By making field names
identical in the source and the target I was able to append new
records to the master file by copy and paste, didn't need the
Merge Layers tool. I prefer not to create too many files.</p>
<p>Thanks again . . . . .<br>

<p>You can use processing algorithm "refactor fields" on the
layer(s) that have fields to be changed. This operation will
give you a temporary file/layer the same number of columns and
-names as the original layer, but with column type(s) redefined
by you. <br>
</p>
<p>Afterwards you can merge the temporary file/layer with the
other layers</p>
<p>Just be sure to have the latest (functioning) version of QGIS
installed: 3.16.3. From the error message you included, I
suspect you have an older version of QGIS installed. I tried to
merge 2 layers using QGIS 3.16.3 and the result was a new layer
that contained the merged layers. If there was a data
discrepancy the result values were null's (but no run-time
errors)<br>

<p>Thanks Bo,</p>
<p>I tried a sample run but it failed:</p>
<p><span style=" color:#ff0000;">"TAG field in layer Tree Table
All 2 PntType has different data type than in other layers
(String instead of integer)</span></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px;
margin-right:0px; -qt-block-indent:0; text-indent:0px;"><span
style=" color:#ff0000;">Execution failed after 1.20 seconds"</span></p>
<p>It looks like it can't handle differing data types and won't
offer choices for merging fields. I wonder if there are other
tools?</p>
<p>Thanks again . . . .<br>
