Hello EBDN Community,

I hope youll doing well

i had a bug please tell to resolve it , or the code snippets which then i can implement in my code any resources which can help me to solve this problem kindly send it to this

or here in the EBDN

I have explained the requirement clearly, unambiguously, and technically.

Below is a clean, professional, step-by-step requirement description written exactly based on:

# 📌 Requirement: Catalog-based Material Selection During Device Generation

## Environment

* **Software**: AUCOTEC Engineering Base (Plant Engineering)
* **Context**: Device generation via custom Assistant / Plug-in (Excel-based generation)
* **Catalog Used**: Standard Catalog

---

## 1. Catalog Structure (MANDATORY)

The catalog is structured as follows:

```
Standard catalog
└─ Materials
└─ Microfinish
├─ XYZ-90
├─ XYZ-89
├─ XYZ-91
```

* `XYZ-90`, `XYZ-89`, `XYZ-91`, are Material catalog entries
* These are not device templates and not FG-based functions
* Each entry represents a material option

---

## 2. Generated Device Attribute

Each generated device already contains the attribute:

```
Purchase Order Data → Material
```

* Attribute name: Material
* Attribute type: Text
* Attribute exists on the device before generation

---

## 3. Required Program Behavior

During device generation (from Excel):

1. The program generates the device (but does NOT store it immediately).
2. The program checks whether the generated device contains the Material attribute.
3. If the attribute exists:

The program must **ask the user to select a material**.
4. The selection dialog must:

Show **ONLY** material entries from
`Standard catalog → Materials → Microfinish`
Example list:

```
XY
XYZ-89
3
```
* **No FG names**
* **No device types**
* **No control-valve / valve entries**
5. The user selects **one material** from the list.
6. The selected value is assigned to:

```
Generated Device → Purchase Order Data → Material
```
7. Only after material selection, the device is stored.

---

## 4. What Must NOT Happen

The following behaviors are **NOT acceptable**:

* ❌ Showing device types like
`Valve, Control-Valve (Process / Fluid)`
* ❌ Showing FG-based templates
* ❌ Showing catalog functions
* ❌ Allowing free-text manual material entry
* ❌ Assigning material after generation is complete
* ❌ Copying attributes instead of values

---

## 5. Timing Requirement (VERY IMPORTANT)

* Material selection must happen **during generation**, not after.
* Progress dialog may pause while the selection dialog is open.
* This is expected and acceptable behavior.



## 6. Expected Result (Final)

After generation:

```
Generated Device
└─ Purchase Order Data
└─ Material = XYZ-91 (or XYZ-89 / XYZ-90)


No manual correction required
Material value is catalog-controlled
Fully consistent with EB best practices

7. One-Line Summary (for EBDN)

> “During Excel-based device generation, the assistant must prompt the user to select a material from Standard Catalog → Materials → Microfinish(folder), and assign the selected catalog material value to the generated device’s Material attribute before storing the device.”*


Kindly help me to resolve these

if any one has code snippets or have codes , resources , already worked in this situation kindly send that to me

Thank you
